The CBI while filing its FIR in 2009 said, "This was perhaps India's biggest corporate fraud case where M/s Satyam Computer Services Limited (M/s SCSL) caused loss to the investors to the tune of Rs.14,162 crore. The company head, Ramalinga Raju and members of his family secured illegal gains to the tune of about Rs.2,743 crore by various tricks. The fraud was perpetrated by inflating the revenue of the company through false sales invoices and showing corresponding gains by forging the bank statements with the connivance of the Statutory and Internal Auditors of the company. The annual financial statements of the company with inflated revenue were published for several years and this lead to higher price of the scrip in the market. In the process, innocent investors were lured to invest in the company. Attempts were made to conceal the fraud by acquiring the companies of kith and kin."
